When I want lasagna, I want unmistakable comfort food. This keto lasagna definitely fits the bill because it is nothing but the good stuff. No zucchini pasta to be found! The best part is this low carb lasagna recipe can be made any night of the week. It's that easy!

I am all about keto dinners that my whole family will eat. If I were to have put zucchini noodles or cabbage noodles in this keto lasagna...they would have turned their nose up really quickly. I could have used homemade keto noodles or egg life wraps, but I really do not think they are needed and add to the calories in this dish.

Making lasagna low carb friendly doesn't take hardly any effort because all you really have to do is remove the noodles. By doing that, and using only 24 ounces of a low carb marinara sauce and 15 ounces of ricotta, we are able to get this keto lasagna down to 8 net carb per serving.

It is super filling on it's own so I really wouldn't pair it with any side. You could serve with a side salad for a vegetable since this is kind of heavy.

I love to use a combo of ground beef and ground sausage for a delicious a full of flavor meat sauce. It really kicks this keto lasagna up a notch!

1 pound ground Italian sausage - I like to use mild Italian sausage for this keto lasagna but you could also use medium or hot sausage. I love the flavor the sausage gives to the lasagna!

1 pound ground beef - I like to use a lean ground beef since we are already using so many other rich ingredients.

24 ounces Rao's marinara sauce - This sauce is really low in carbs and tastes amazing in low carb lasagna! I love that it is uses simple ingredients (tomatoes, olive oil, onions, salt, garlic, basil, black pepper and oregano)

15 ounces ricotta cheese - you could use low fat ricotta or full fat. They both have the same amount of carbs.

What could I use as keto noodles?

I have seen people make their own keto lasagna noodles out of cheese. In my opinion that is just too much cheese and adds lots of extra calories.
You could use egg life wraps cut into strips
I have heard of people using lunch meat
Of course there is zucchini lasagna noodles which is very common
A commenter let me know they now have hearts of palm pasta that is very similar to lasagna noodles. Those are definitely worth a try.
